You can check out the article yourself, but I always have a hard time with maps like this. I start thinking of people I know from different countries to see if they fit the map. Of course, this is nonsense as there are more and less emotional people in every country, but in general I still enjoy thinking about these things (and an excuse to look at a map in a new way is always fun).
According to Gallup, Singapore is the least emotional country whereas nearby Philippines is the most emotional. There are other trends that can be witnessed here. Russia and the old Soviet Bloc nations tend to be less emotional. The Americas tend to be more emotional.
One thing I wish was that the map for the United States was broken down by state. As I've traveled around our country, I've noticed that the upper Midwest in particular tends to be rather stoic.
